Joint Navigation Warfare Center (JNWC) IV
RFP: FA2518-22-R-0027
Section J Attachment 5: J9 Engineering Support Scenario
J9 Engineering Support Scenario
Question1: (Tradeable). If tasked to complete GPS receiver testing against electromagnetic interference (EMI) in a hardware in the loop setup, how would you estimate or calculate the GPS signal power for each individual SV and/or the total combined power of all SVs. And, assuming any additional hardware or software is readily available how would you accurately measure the power for each individual SV and/or the total combined power of all SVs. Assume the setup uses a FRPA GPS puck with a 30dB LNA connected to a GPS receiver and that the setup can connect a GPS simulator to control SV generation and you have access to any other equipment you need.
Question 2: (Acceptable/Unacceptable). What is the relative power difference between the two AWGN (additive white Gaussian noise) signals below (hint there is no need to calculate the total power for each signal). You can provide an answer in dB.
